Farsightedness is an abnormality of the refractive system in which light rays passing through the cornea and the lens do not fall exactly on the retina, but behind it, which is called hyperopia. Farsightedness can be corrected with farsightedness glasses, but it is different from presbyopia. Presbyopia is caused by a decline in regulation, which makes it difficult to see clearly up close, while hyperopia is caused by a problem with the refractive system, which is normal. In the case of farsightedness, the degree of presbyopia will be more severe after the age of 45. In the case of aging farsightedness, a higher degree of fancy glasses is needed to correct it. Farsightedness and presbyopia are different concepts, but both are corrected in the same way, and both need to be corrected with farsighted glasses.
